ABSTRACT:
A full face safety helmet comprises a helmet portion, of the usual, generally part spherical form adapted to cover and protect the wearer's skull, and a chin guard member in the form of a closed loop of impact resistant material. The chin guard member has inwardly inclined side walls, and the bottom of the helmet is received in these side walls as an interference, cone-and-wedge fit. The chin guard member also has protruberances on its side walls adapted to engage the lower forward edge of the helmet portion, to protect the wearer against blows on the front of the chin guard member. The helmet portion and chin guard member are releasably secured together, so that the helmet can if desired be used as a full coverage safety helmet, without the chin guard.
